Question
Asked 14th Nov, 2015

How can I minimize cell stress and decreasing cell adherent during scratch assay on fibroblast cells? How can I optimize scratch assay?

When I triggered scratch assays on Human fibrablast cells, at that time there was no problem; I made wound properly, cells were adherent. I took images for first time point (0h), But, 24 h later there was  no adherent cell ( not wound area) in some wells.  I always took care about wound, washing  ( minimum;once) and aspiration steps.(I tried to minimize all stress factors to effect cells or wound process). But, still, problem is proceeding.
How can I solve this problem?
Thank you for your concern.

But, this problem occured not in all well. In few wells cell detaching and stress were seen.

I hope I understand your meaning of "cell swelling". The cells will try to spread out more after scratch so that they can heal off the scratch. So, why is that a concern? Hope I did not make a mistake.

Not healing occured. After washing step, cells got stressed and 24 h later  numbers of adherent cells got decreased in some wells
Thank you.
Fibroblasts need fresh food, change medium often to over come this problem. Cells stressed due to lack of place to divide, lack of food, and decreasing survival due to stress. To avoid such conditions use your scratch analysis when your cells reached 80% confluence and follow with change of medium every 24h, just do the same for your control as for proper comparison.
